By adjusting the gas pressure to control the torque size, to allow specific torque requirements to be set, each tool is equipped with a dedicated air pressure first to the torque of the control chart and calibration report.

And for further application, pneumatic torque wrench can also be used with torque sensors, the output torque is more accurate. After obtaining the required torque, use a suitable circuit system to manually or automatically turn off the air supply.
